Answer: A bike
A bike is composed of various simple machines. It has a wheel and axle as one component, and it also has screws to hold the various parts together, along with levers and pulleys that are connected to the pedals. So all of these simple machine concepts work together to help transport the rider from point A to point B.
The other answer choices of screw, inclined plane, and lever, are fairly simple machines that don't have many things going on at once compared to a bike.
The reason people describe water as a universal solvent is because it dissolves almost anything.
Answer: As altitude rises, air pressure drops.
Explanation: As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.
Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.02 atm
V = Volume of gas = 150.0 ml = 0.15 L
n = number of moles of carbon dioxide = ?
R = gas constant =
T =temperature =
According to stoichiometry:
2 moles of carbon dioxide require = 2 moles of sodium peroxide
Thus 0.006 moles carbon dioxide require= moles of sodium peroxide
Mass of sodium peroxide needed for 24 hour=
Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.
